Ethnobotanical uses of piscicidal plants
Harvesting of fish using piscicidal (fish poisoning) plants has been a common practice by the tribal people of Nagaland. The present study documents the piscicidal plants and their usage based on the information acquired from the local community. Many of these plants besides piscicidal property possess other therapeutic properties which are used in traditional medicines. Seventeen piscicidal plants which are traditionally used for fish catching and in preparation of local medicine from the state of Nagaland have been recorded, along with plant parts, viz. roots, bark, leaves, fruits and seeds. The paper enumerates and discusses the piscicidal and ethnobotanical utilization of these plants and their bio-active compounds. Some of these plants may have application in fish nursery management by local farmers substituting for rotenone.
